Bodyboard
Bodyboarding is a water sport in which the surfer rides a bodyboard on the crest, face, and curl of a wave which is carrying the surfer towards the shore. Bodyboarding is also referred to as ''Boogieboarding'' due to the invention of the "Boogie Board" by Tom Morey in 1971. The average bodyboard consists of a short, rectangular piece of hydrodynamic foam. Bodyboarders typically use swim fins for additional propulsion and control while riding a breaking wave. Origin Bodyboarding originates from an ancient form of riding waves (surfing) on one's belly. Indigenous Polynesians rode "'' alaia''" (pronounced ah-lie-ah) boards either on their belly, knees, or feet (in rare instances). '' Alaia'' boards were generally made from the wood of '' Acacia koa'' and varied in length and shape. They are distinct from the modern stand-up surfboards in that they had no ventral fins. Captain Cook recorded seeing Hawaiian villagers riding such boards when he came to Hawaii in 1778. The boards ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Bat Tail

Bodyboarding is also referred to as ''Boogieboarding'' due to the invention of the "Boogie ... design, Bat tail is used to describe a style of tail which was invented by Mike Stewart in the mid-1990s. The bat tail is essentially a combination of the clipped crescent tail and the square tail, which provides a balance of control and maneuverability. The additional "hump" located between the two outside tail pegs increases the tail's surface area, consequently elevating the rider's legs further out of the water and as a result, this reduces drag on the wave face. It is so named because when viewing the board bottom with the nose down, the outline of the tail somewhat resembles the ears and dome of the Batman's cowl. This results in increased looseness and speed with a reduction in stability (as com ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tom Morey
Tom Hugh Morey (15 August 1935 – 14 October 2021), also known by the moniker Y, was a musician, engineer, surfboard shaper, and surfer responsible for several technological innovations that have heavily influenced modern developments in surfing equipment design. Biography Morey was born in Detroit, Michigan in 1935. By 1944, he was living in Laguna Beach, California, and was avidly developing his talent for drumming. He became a professional musician in the 1950s. He was an avid performer of jazz. While surfing as a hobby he attended the University of Southern California and graduated with a B.A. in mathematics in 1957. He married Jolly Givens in 1958 and worked for Douglas Aircraft, as a process engineer in composites. After Douglas, he worked a series of jobs involving composite materials and processes, which he applied to his surf-related inventions. He left the corporate world for good in 1964, moved to Ventura and started a series of companies that served the surfing mar ...

Surfing
Surfing is a surface water sport in which an individual, a surfer (or two in tandem surfing), uses a board to ride on the forward section, or face, of a moving wave of water, which usually carries the surfer towards the shore. Waves suitable for surfing are primarily found on ocean shores, but can also be found as standing waves in the open ocean, in lakes, in rivers in the form of a tidal bore, or wave pools. Surfing includes all forms of wave-riding using a board, regardless of the stance. There are several types of boards. The Moche of Peru would often surf on reed craft, while the native peoples of the Pacific surfed waves on alaia, paipo, and other such watercraft. Ancient cultures often surfed on their belly and knees, while modern-day surfing is most often ''stand-up surfing'', in which a surfer rides a wave while standing on a surfboard. Another prominent form of surfing is body boarding, where a surfer rides the wave on a bodyboard, either lying on thei ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Swimfin
Swimfins, swim fins, diving fins, or flippers are finlike accessories worn on the feet, legs or hands and made from rubber, plastic, carbon fiber or combinations of these materials, to aid movement through the water in water sports activities such as swimming, bodyboarding, bodysurfing, float-tube fishing, kneeboarding, riverboarding, scuba diving, snorkeling, spearfishing, underwater hockey, underwater rugby and various other types of underwater diving. Swimfins help the wearer to move through water more efficiently, as human feet are too small and inappropriately shaped to provide much thrust, especially when the wearer is carrying equipment that increases hydrodynamic drag. Very long fins and monofins used by freedivers as a means of underwater propulsion do not require high-frequency leg movement. This improves efficiency and helps to minimize oxygen consumption. Short, stiff-bladed fins are effective for short bursts of acceleration and maneuvering, and are useful fo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Acacia Koa
''Acacia koa'', commonly known as koa, is a species of Flowering plant, flowering tree in the Family (biology), family Fabaceae. It is Endemism, endemic to the Hawaiian Islands, where it is the second most common tree. The highest populations are on Hawaii (island), Hawaii, Maui and Oahu, Oahu. Name The name ''koa'' in the Hawaiian language ultimately comes from Proto-Austronesian language, Proto-Austronesian *''teRas'' meaning "core" or "ironwood"; many names referring to certain ironwood or heartwood species in Southeast Asia and Oceania such as ''Vitex parviflora'' (''tugás'' in Cebuano language, Cebuano), ''Eusideroxylon zwageri'' (''togas'' in Tombonuwo language, Tombonuwo), and ''Intsia bijuga'' (''dort'' in Palauan language, Palauan) descend from this root. The Hawaiian Acacia koa is closely related to a common tree in Taiwan called ''Acacia confusa''. The two species also share a very similar appearance. ''Koa'' also means brave, bold, fearless, or warrior. Description ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Polystyrene
Polystyrene (PS) is a synthetic polymer made from monomers of the aromatic hydrocarbon styrene. Polystyrene can be solid or foamed. General-purpose polystyrene is clear, hard, and brittle. It is an inexpensive resin per unit weight. It is a poor barrier to air and water vapor and has a relatively low melting point. Polystyrene is one of the most widely used plastics, with the scale of its production being several million tonnes per year. Polystyrene is naturally transparent to visible light, but can be colored with colorants. Uses include protective packaging (such as packing peanuts and optical disc jewel cases), containers, lids, bottles, trays, tumblers, disposable cutlery, in the making of models, and as an alternative material for phonograph records. As a thermoplastic polymer, polystyrene is in a solid (glassy) state at room temperature but flows if heated above about 100 °C, its glass transition temperature. It becomes rigid again when cooled.

Polypropylene
Polypropylene (PP), also known as polypropene, is a thermoplastic polymer used in a wide variety of applications. It is produced via chain-growth polymerization from the monomer Propene, propylene. Polypropylene belongs to the group of polyolefins and is Crystallization of polymers#Degree of crystallinity, partially crystalline and Chemical polarity#Nonpolar molecules, non-polar. Its properties are similar to polyethylene, but it is slightly harder and more heat-resistant. It is a white, mechanically rugged material and has a high chemical resistance. Polypropylene is the second-most widely produced Commodity plastics, commodity plastic (after polyethylene). History Phillips Petroleum chemists J. Paul Hogan and Robert Banks (chemist), Robert Banks first demonstrated the polymerization of propylene in 1951. The stereoselective polymerization to the isotactic was discovered by Giulio Natta and Karl Rehn in March 1954. This pioneering discovery led to large-scale commercial producti ...

Foam
Foams are two-phase materials science, material systems where a gas is dispersed in a second, non-gaseous material, specifically, in which gas cells are enclosed by a distinct liquid or solid material. Note, this source focuses only on liquid foams. Note, this source also focuses on liquid foams. Foam "may contain more or less liquid [or solid] according to circumstances", although in the case of gas-liquid foams, the gas occupies most of the volume. In most foams, the volume of gas is large, with thin films of liquid or solid separating the regions of gas. Etymology The word derives from the Old High German, medieval German and otherwise obsolete ''veim'', in reference to the "frothy head forming in the glass once the beer has been freshly poured" (cf. ''ausgefeimt''). Structure A foam is, in many cases, a multi-scale system. One scale is the bubble: materials science, material foams are typically randomness, disordered and have a variety of bubble sizes. At larger siz ...
